A Piano by Jason Schwartzman, a Mirror by Seth Rogen, an Armchair by Narciso Rodriguez, and Other Celebrity Collaborations from Field Studies

"I'm always skeptical of homes that don't have any musical instruments or a dog," musician and actor Jason Schwartzman quipped yesterday at Sight Unseen Offsite, the beloved design blog's annual appearance IRL. He was on hand to present a stylish option for those lacking in the former: Marzipan Pianette, a petite ivory-hued console that opens to reveal a sweet set of keys—a 1970s Hohner Clavinet Pianet, to be exact. Schwartzman collaborated with Los Angeles–based interiors studio Wall for Apricots, co-founded by Katy Burgess and Schwartzman's wife, Brady Cunningham, on the piece. "I really just want to sit down and play," he said with boyish excitement.

This buzzy collaboration is part of the Sight Unseen exhibition "Field Studies," where cofounders Jill Singer and Monica Khemsurov played matchmaker, pairing 13 furniture and interior designers with creatives from the worlds of food, music, fashion, film, and art. Seth Rogen explored his passion for '80s interiors by designing a beach-ball-esque mirror with Brooklyn-based Bower studios; interior designer Kelly Behun and fashion legend Narciso Rodriguez put their heads together on an inventive armchair; and Drew Seskunas of The Principals helped musician Angel Olsen realize one of her ultimate dreams—to give physical form to a song—by creating a machine that could translate sound frequencies into wax forms that can be cast into aluminum candlesticks. The icing on the cake? All of the high-end designs, for sale on 1stdibs.com/sightunseen, will be sold to benefit a charity of the designers' choice.
